Dr. Young asked us to take Charlotte to Lurie Children’s for an exercise test prior to surgery. Since one of Charlotte’s reported symptoms has been “heart pain” when her heart rate accelerates, Dr. Young wanted to get a baseline understanding of how exertion is effecting her heart and lung function.
The test took about an hour. First, Charlotte had to breathe into a tube that didn’t look like any other breathing test I’ve seen. Once she mastered the skill, she had to blow the bowling ball to knock down the pins–yep, the device was hooked to a computer and she used her breath to operate a computer game.
As happens with an adult “stress” test, the technician then hooked Charlotte up to the EKG machine. Charlotte walked on a treadmill up an incline that increased in pitch and speed every three minutes. The goal was to get her to achieve maximum exertion, stopping when she could go no further. She almost made it there–after about 7 1/2 minutes, the tube (into which she was still breathing while she walked/ran) had caused dry mouth that she just couldn’t handle, so she called “uncle” a wee bit early.
The cardiologist–in the room reading the EKG while she did the test–said that preliminary results indicated a 71% lung function; most kids her age should have 80%. Best, news–no arrhythmia while she worked out, no reason for immediate concern (or emergency intervention), and NO PAIN while she ran.
